RefuelingFuel filler door
Before refueling, shut the engine
off. If the engine is running, fuel
cannot be filled into the tank and the
Service Engine lamp may come on.<
To open the filler door, press on the
front edge.
To unlock the filler door if the central
locking system fails, refer to page 180.
When handling fuels, comply with
all of the applicable safety precau-
tions and regulations pertaining to
fuels.
Never carry spare fuel containers in
your vehicle. Whether empty or full,
these containers can leak, cause an ex-
plosion, or lead to fire in the event of a
collision.<
394de011
Simple and friendly to the
environment
Open the filler cap carefully to
prevent fuel from spraying out.
Fuel spray may cause injury.
Do not top off. Topping off may cause
fuel spillage.<
Keep the filler cap in the bracket
attached to the fuel filler door.
390de603
When refueling, insert the filler nozzle
completely into the filler pipe. Pulling
the nozzle out of the pipe during refuel-
ing
>results in premature pump shutoff
and
>will reduce the effect of the vapor
recovery system on the pump.
Close the fuel cap carefully after
refueling. A loose or missing cap
will activate the Service Engine lamp.<

Starting the engineBefore starting>Engage the parking brake
>Be sure that the transmission selector
is in "Neutral" (or "Park" if the vehicle
is equipped with an automatic trans-
mission)
>Step on the clutch pedal.
Do not allow the engine to run in
enclosed spaces. The exhaust
gases contain carbon monoxide, an
odorless and colorless, but highly toxic
gas. Breathing the exhaust gases poses
an extreme health risk, and can lead to
unconsciousness and death.
Never leave the car unattended with the
engine running. An unattended vehicle
with a running engine represents a po-
tential safety hazard.<
Starting the engine>Start the engine. Do not press the
accelerator pedal.
BMW 528i, BMW 540i with man-
ual transmission:
Do not actuate the starter for too short
a time. Do not turn it for more than ap-
prox. 20 seconds. Release the ignition
key immediately as soon as the engine
starts.
Do not allow the engine to warm up by
leaving it running while the vehicle re-
mains stationary. Instead, begin driving
immediately at a moderate engine
speed.
BMW 540i with automatic transmission:
Your BMW is equipped with the conve-
nience starting feature. Simply turn the
key to position 3 (starter) and then re-
lease it immediately.
The starter continues to operate auto-
matically.
The automatic starting mode will not
operate if the battery voltage is low.
Should this condition arise, it remains
possible to jump-start the engine (refer
to page 182).<
Should the engine fail to start on the
first attempt (if it is very hot or cold, for
instance):
>Press the accelerator pedal halfway
down while engaging the starter.
Cold starts at extremely low tempera-
tures, from approx. +57 (Ð156)
and at elevations above 3,300 feet
(1,000 meters):
>It may be necessary to allow the
starter to remain engaged somewhat
longer than under normal operating
conditions (approx. 10 seconds)
>Press the accelerator pedal halfway
down while engaging the starter.
Engine idle speed is controlled by the
engine computer system. Increased
speeds at startup are normal and
should decrease as the engine warms
up. If engine speed does not decrease,
service is required.
To prevent the battery from discharg-
ing, always deactivate electrical de-
vices which are not in use. Switch the
ignition off when the vehicle is not
being driven.

Break-in procedureTo ensure that your vehicle provides
maximum economy throughout a long
service life, we request that you ob-
serve the following:Engine and differentialUp to 1,200 miles (2,000 km):
Drive at varying engine speeds and road
speeds, but do not exceed 4,500 rpm
and the following road speeds during
this initial period:
BMW 528i: 100 mph (160 km/h)
BMW 540i: 106 mph (170 km/h)
Obey your local and state maximum
speed limits.
Refrain from using full throttle and avoid
pressing the accelerator beyond the
kickdown point.
Once you have driven 1,200 miles
(2,000 km), engine and vehicle speeds
can gradually be increased.
You should also comply with these
break-in procedures if the engine or dif-
ferential is replaced later in the course
of the vehicle service life.
TiresDue to technical factors associated
with their manufacture, tires do not
achieve their full traction potential until
an initial break-in period has elapsed
for this reason, drive with extra care
during the initial 200 miles (300 km).
Obey your local and state maximum
speed limits.
When the vehicle is operated on
wet or slushy roads, a wedge of
water may form between the tire and
the road surface. This phenomenon is
referred to as aquaplaning, or hydro-
planing, and can lead to partial or com-
plete loss of traction, vehicle control
and braking effectiveness. Reduce your
speed on wet roads.<
Brake systemApproximately 300 miles (500 km) must
elapse before the brake pads and rotors
achieve the optimal pad-surface and
wear patterns required for trouble-free
operation and long service life later on.
To break in the separate parking brake
drums, apply the parking brake lightly
when coasting to a standstill (at a traffic
signal, for instance), provided that traf-
fic conditions allow you to do so. To
avoid corrosion, repeat this procedure
from time to time.
The brake lamps do not come on
when the parking brake is applied.
Vacuum for the brake system servo unit
on your BMW is available only when the
engine is running. When you move the
car with the engine shut off Ð when
towing, for instance Ð substantially
higher levels of pedal force will be
required to brake the vehicle.<

128n
Antilock Brake System (ABS) Disc brakesInformation for your safetyNot even ABS can suspend the laws of
physics. ABS alone cannot prevent
accidents when the brakes are applied
without an adequate safety interval
between vehicles, if the car is driven at
an excessive rate of speed in curves, or
if aquaplaning occurs. Responsibility for
these types of situations remains in the
hands (and at the feet) of the driver.
You should never allow the added
safety of ABS to lull you into a false
sense of security, or mislead you into
taking increased risks that could affect
your own safety and that of others.
Do not make any modifications to
the ABS system.
Service procedures on ABS are to be
performed by authorized technicians
only.<
In the event of a fault
If the ABS warning lamp in the
instrument cluster comes on,
refer to page 23. The brake
system then reverts to conven-
tional operation as on vehicles
without ABS. However, have the
brake system checked by your BMW
center as soon as possible. To prevent
undetected defects and cumulative
faults from adversely affecting the brake
system, refer any problems to your
authorized BMW center at the earliest
opportunity.
Disc brakes furnish optimum decelera-
tion and braking control and greater
fade resistance under heavy use.
When the vehicle is driven only occa-
sionally, during extended periods when
the vehicle is not used at all, and in
operating conditions where brake appli-
cations are less frequent, there is an
increased tendency for corrosion of the
rotors and accumulation of contamina-
tion on the brake pads. This occurs
because the minimal pressure which
must be exerted by the pads during
brake applications to clean the rotors is
not reached.
If the brake rotors are corroded, they
will tend to respond to braking with a
pulsating effect which even extended
application will fail to cure.
For your own safety: Use only
brake pads that BMW has
approved for your specific vehicle
model. BMW cannot evaluate non-
approved brake pads to determine if
they are suited for use, and therefore
cannot ensure the operating safety of
the vehicle if they are installed.<
